Pass XP-17 and Hana ML loading question


Guys anyone here has any experience with the Pass XP-17 settings for Hana ML?

I just switched form Pass XP-15 to 17 and its totally different animal. 

Just to compare them both with the gain set at 66db and loading 333ohm they act completely different, while 15 gets maximum bottom and fantastic detail 17 sounds great at the top and the midrange but bottom needs improvement.  Would anyone run 47K ohm?

And what I meant by saying "terrible" was, sporrans and mid got clipped about 30%  while bass got big but hollow and muddy no definition at al just slams of senseless sonic boom,  and on top of that when record ended and I raised arm I heard harmonics between speakers and cartridge. I went bac to 1k setting and now over 4th weekend I'll experiment with all settings I have between 500 ohms and 1k to see if there is anything else I can squeeze out of the system.

@ssg308 Check your phono cartridge wiring to make sure the connections are right. If you got one channel backwards it would sound exactly like this!

Which is what I said, too. But it can’t be at the cartridge because he reports relatively good results with all other choices of load R. Which is why I suggested there may be a phase error incurred in relation to wiring of the load selector switch, when he sets load to 47K. Or something like that is reversing phase in one channel, only when 47K is selected.

I can make sure it is connected correctly, How would I know what color on cartridge is corresponding with +post  and what color is what channel ? where I can find diagram ?

If you think it is possible I will call to Pass labs and have conversation with the tech.

Both amps seam to act the same way when comes to the 47k load.

Anyhow I'll report back what Pass has to say about it. 

Until now, you never revealed that both the XP 15 and the XP 17 had this sonic character when you set the load to 47K ohms. Since you used the term “amps”, is it correct to assume that you mean both phono stages? If so, I am stumped, because it is highly unlikely that both phono stages were miswired at the factory. So by all means call Pass labs. I would be interested in what they say.
